I had taught my grandma how to use a feature-phone and she was pretty happy with it. Later she was diagnosed with dementia, that phone's battery is dead for some years now. Somewhere down the line, she forgot how to use her phone (and pretty much anything else). It's sad watching her unlearn things.
Not to mention my old Mac Mini I gave her after installing Windows 7 that she lets her students use when she tutors.
My dad has his own 17 inch Dell that he uses and he loves the Roku TV that I got him for Father’s Day.
Even worse, they already had DSL but they got cable internet when I stayed there for the summer and was working remotely. She kept both just in case one started acting flaky.
She uses Word and Publisher all of the time.
It helps that my mom is a retired high school teacher and we always had computers in the house since 1986.
